OBIT: [I believe this is Lillian's mother's obituary but have no direct proof. Lillian's husband died very early so it's entirely possible that she remarried and became Becker. Also, her father-in-law may have lived on S. Kedzie in 1910 (per the census) which gives this couple the opportunity to meet as the addresses are only a few houses apart.]

His father, James, died when Raymond was only 9 months old.

CENSUS:
1920 - ED 2176, Sheet 4B, Ward 34, 2342 S. Central Park Ave., Chicago, Illinois
For some reason, Raymond, after the death of his father, is now living with Lillian Krivaky (or Krivsky) and her children and is listed as her "step-son". I don't quite understand this relationship. As far as I know, James Rozhon was married to Lillian Julia Koca (info obtained from the George Baley website - see above for URL). So how does this other Lillian fit into the picture? Did she adopt Raymond? Is she some sort of relative of Raymond's mother?
